Development of hepatic CT perfusion software on personal computer / 中华放射学杂志

ABSTRACT

Objective To develop hepatic CT perfusion software on personal computer (PC), and to calculate hepatic perfusion parameters and render pseudo color perfusion image Methods A DICOM supported platform was developed on PC with Delphi 7 0, including DICOM data reading, storage, and display interfaces Hepatic CT perfusion software (PerfX) was developed upon this platform Results This software was based on Windows 2000/XP system, which could run smoothly on a computer with CPU above 500 MHz and RAM above 128 MB It could calculate hepatic arterial perfusion, portal venous perfusion, and hepatic perfusion index of region of interest, and show anatomic and functional details within one pseudo color perfusion image Conclusion A complete post processing was finished on PC by using PerfX, from DICOM data support to arithmetic analysis:
